Modern MEMS gyroscope designs are highly optimized and are therefore a particularly good example of a device that must be carefully optimized not only for performance, but also for insensitivity to manufacturing variation.

Converting rotation to Coriolis force is the basis of gyro operation. A primary or a seed motion is needed in a gyro; the Coriolis force is the result of two orthogonal motions and is orthogonal to both of them. In MEMS gyros the primary motion cannot be continuous rotation as in conventional ones due to a lack of good bearings in MEMS.
